PROMOTES STRONG BONES: Vitamin D helps with regulating absorption of calcium and phosphorus. It's important to get enough vitamin D to ensure bones and teeth are strong. SUPPORTS THE IMMUNE SYSTEM: Vitamin D supports immune function. Having sufficient levels of vitamin D helps trigger peptides, which allow your body to quickly and effectively fight off invaders. SUPPORTS CARDIOVASCULAR FUNCTION & COGNITIVE HEALTH: In addition to supporting strong bones and the immune system, Vitamin D also helps support cardiovascular function and cognition. Vitamin D receptors are found throughout the nervous system and in the brain's hippocampus, which makes this vitamin's role even more far-reaching than we knew.
